Free Markdown editor: write and preview Markdown with live rendering in your browser

How the Markdown editor works and what formatting it supports

This Markdown editor renders a live preview of your Markdown as you type, with no delay or button clicks. It uses a client-side Markdown parser that supports all CommonMark elements: headings (H1-H6), bold, italic, bold+italic, strikethrough, inline code, fenced code blocks, unordered and ordered lists, blockquotes, horizontal rules, links, and images. The three view modes, split, source only, and preview only, let you focus on writing or reviewing the output.

The editor is useful for writing README files, blog posts, documentation, and any content that will be published through a Markdown-compatible CMS or platform. All processing runs in your browser. Your content is never sent to any server.

FAQ

Frequently asked questions about Markdown editing and formatting

What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax to produce HTML. For example, wrapping text in **double asterisks** makes it bold, # at the start of a line creates a heading, and - at the start creates a bullet list. Markdown is designed to be readable as plain text even without rendering. It's the standard format for README files on GitHub, documentation platforms like GitBook, static site generators, and content management systems.
What Markdown flavour does this editor use?
This editor implements CommonMark-compatible Markdown. The standard subset that works across most platforms. It supports all core Markdown elements: headings (# through ######), bold, italic, bold+italic, strikethrough, inline code, fenced code blocks, blockquotes, ordered and unordered lists, horizontal rules, links, and images. It doesn't include GitHub Flavored Markdown extensions like tables or task lists, but covers everything needed for standard documentation and writing.
How do I create a table in Markdown?
Standard Markdown doesn't include tables, but GitHub Flavored Markdown (GFM) does. The syntax is: | Column 1 | Column 2 | on one line, | --- | --- | on the next (the separator row), then | Value 1 | Value 2 | for each data row. This editor uses standard CommonMark which doesn't render tables. For table support, use a GFM-compatible tool like GitHub itself, GitBook, or a documentation platform that supports GFM extensions.
Can I export the HTML output?
Yes. Use your browser's copy feature to copy the rendered preview HTML, or copy the raw Markdown from the editor and paste it into your target platform. Most blogging platforms, CMSs (WordPress, Ghost, Contentful), and documentation tools accept Markdown directly. If you need raw HTML, open your browser DevTools (F12), inspect the preview pane, and copy the inner HTML from there.
